Other corticosteroid-containing products, unless prescribed by the doctor.
Medications that inhibit the enzyme CYP3A4 (e.g., ritonavir, itraconazole), since these drugs may inhibit the metabolism of corticosteroids and may increase the patient's exposure to mometasone. The clinical relevance of this interaction depends on the dose and route of administration of the corticosteroid and the potency of
the CYP3A4 inhibitor.
Concomitant use with other topical products, since the efficacy, safety, and stability of mometasone furoate cream or ointment may be altered.
The patients should tell their doctor if they are using, have recently used, or might use any other medicine.
